House Vendrien

 is one of the major houses of Apex and Vendrien's Well. It was responsible for reforming the realm into an absolutist monarchy following the defeat of Apex by a coalition of Haven, Azure, and Stalwart in 312 TR, remaining as militant and defiant as ever. The house was crushed by Kyros' forces in 429 TR, as the Kingdom was brought to heel and annexed into the Empire. Remnants of the house became the nucleus of an anti-Imperial insurgency in 431, as the Vendrien Guard.

Vendrien Alanta, then head of House Vendrien, was the last Queen of Apex.
